The formula C8H18 of octane, the eighth member of the alkane. There are 18 isomers (22 if stereoisomers are included). One of these isomers,2, 2, 4-trimethylpentane, has a low knock rate when used as gasoline engine fuel and is therefore rated as the 100 octane rating. The 18 isomers are: n-octane; 2-methylheptane; 3-methylheptane; 4-methyl heptane; 2, 2-dimethylhexane; 3, 3-dimethylhexane; 3-ethylhexane; 2, 3-dimethylhexane; 2, 4-dimethylhexane; 2, 5-dimethylhexane; 3, 4-dimethylhexane; 2,3, 4-trimethylpentane; 2,2, 3-trimethylpentane; 2,2, 4-trimethylpentane; 2,3, 3-trimethylpentane; 2-methyl-3-ethylpentane; 3-methyl-3-ethylpentane; 2,2,3, 3-tetramethylbutane.
